  In view of such a conventional situation, the present invention is a method for manufacturing a phosphorescent body capable of efficiently producing a granular phosphorescent body with simple equipment, a phosphorescent body manufactured thereby, and a nail using the phosphorescent body. The purpose is to provide stones.

  In order to achieve the above object, a method of manufacturing a phosphorescent material according to the present invention is characterized in that, in the phosphorescent material manufacturing method containing at least a phosphorescent material and a glass material, at least the phosphorescent material and the glass material are mixed and pasted. The mixture is laminated in a plurality of layers to form a granular laminate, and the laminate is baked to be melted and molded by surface tension in a molten state.

  According to the above configuration, since the laminate has a structure in which paste-like mixtures are laminated, the laminate before firing has low fluidity. By baking the laminated body so as to melt, the laminated body becomes more fluid and becomes liquid, and surface tension is generated in the laminated body. The surface tension is a tension that acts along the surface so that the surface contracts by itself to have as small an area as possible, and the tension is generated according to the shape of the laminate. Further, the surface tension varies depending on the type of liquid. Therefore, the shape changes depending on the surface tension in the molten state, and can be formed into a desired shape.

  The formed laminate is preferably moved to a furnace and fired by a resin support layer having adhesiveness to the laminate. Since the resin-made support layer is burned off by firing, the phosphor can be manufactured more efficiently.

  In this case, the laminate is preferably formed by sequentially laminating on the surface of the support layer, and the firing is performed with the laminate oriented on the support layer. A laminated body can be formed on a resin and can be easily formed by printing or the like. Moreover, since the laminate is fired in a state where it is located on the support layer, it is possible to suppress the adverse effect on the surface of the phosphor after firing, and to improve the finishing accuracy.

  Further, the support layer is a transfer layer of a transfer paper, and the transfer paper is provided on the mount via an adhesive layer made of a water-soluble material, and the transfer paper is immersed in water by being immersed in water. It is desirable to dissolve the adhesive layer and separate the transfer layer from the mount while holding the laminate, and move it to a furnace. Thereby, since a laminated body is formed on the transfer paper which has a mount, dimensional accuracy improves more. In addition, the transfer layer can be formed thin, so that it can be easily separated from the mount by soaking in water, and the working efficiency is further improved.

  And since what was laminated | stacked should just be baked, a manufacturing facility is simple. In addition, since a large number of laminates may be formed at the same time, the manufacturing efficiency is good and the accuracy is stable.

  In such a case, it is desirable that the phosphorescent material is desirably blended so as to be 1 wt% or more and 40 wt% or less with respect to the total amount of the phosphorescent material and the glass material. If it is in this numerical range, the light emission performance by the phosphorescent material can be maintained, and the molding can be performed with a stable accuracy by the surface tension.

  The said laminated body may be formed from the multiple types of mixture from which the compounding quantity of the said luminous material differs. Moreover, the said laminated body may be comprised from the multiple types of layer from which the area of the said layer differs. By differentiating the amount of the phosphorescent pigment and the amount of the glass material in the layer of the laminate, a difference in surface tension occurs, and the desired shape can be stably molded with high accuracy.

  A coat layer made of the glass material may be provided below and / or above the uppermost layer of the laminate. When the content of the phosphorescent material is increased, the phosphorescent pigment present on the surface of the phosphorescent material to be produced causes irregularities on the surface and the smoothness decreases. By making the lowermost layer and / or the uppermost layer a coating layer made of a glass material, smoothness can be improved. Moreover, the light emission performance can be maintained by using a glass material.

  The thickness of the coat layer may be different from that of other layers. Thereby, a precise shape can be obtained and a thick laminate can be formed. Therefore, it is possible to efficiently generate a phosphor with good light emission performance.

  And the said laminated body is good to form by performing screen printing in multiple times. Manufacturing equipment is simple, many can be created simultaneously, and manufacturing efficiency is good.

  The mixture contains medium and is preferably dried each time the layer is formed. If the organic solvent contained in the medium remains at the time of firing, it becomes sooted and darkened. By drying each time a layer is formed, the organic solvent is vaporized to prevent a decrease in light emitting performance. The phosphorescent body manufactured by any one of the above phosphorescent body manufacturing methods can be used as, for example, a nail stone.

  According to the method for producing a granular phosphor according to the present invention and the characteristics of the phosphor for producing the phosphor and the stone for nail using the phosphor, it is possible to efficiently produce a granular phosphor with simple equipment. It became.

(A)-(c) is a front view which shows the laminated body of other embodiment. It is a figure equivalent to Drawing 3 (c) showing other embodiments.

Next, a first embodiment of the present invention will be described with reference to FIGS.
The phosphor 1 according to the present invention is a granular sintered body containing at least a phosphorescent pigment as a phosphorescent material and a glass frit as a glass material. The phosphorescent body 1 is formed by laminating a paste-like mixture 2 prepared by mixing phosphorescent pigments and glass frit in a plurality of layers to form a granular laminate 3, and firing the laminate 3 so as to melt it. And molded by the surface tension in the molten state.

  As shown in FIG. 1, the phosphor 1 according to the first embodiment has a substantially cubic shape. This phosphorescent body 1 is obtained by firing a granular laminate 3 as shown in FIG. As shown in FIG. 2A, the laminated body 3 includes a phosphorescent layer 31 having a six-layer structure made of the mixture 2 and coat layers 30 and 32. As shown in FIG. 2B, the laminate 3 has a substantially square shape in plan view.

  The phosphorescent layer 31 includes a lower layer portion 33 composed of the first layer 31a to the third layer 31c and an upper layer portion 34 composed of the fourth layer 31d to the sixth layer 31f. As shown in FIG. 2B, in the present embodiment, the area of the surface orthogonal to the stacking direction is larger in each of the layers 31 a to 31 c in the lower layer portion 33 than in each of the layers 31 d to 31 f in the upper layer portion 34. When the area of each layer is made different between the upper side and the lower side of the phosphorescent layer 31, the surface finish of the phosphorescent body 1 becomes smooth. In the present embodiment, for example, the side length L of the upper layer portion 34 is set to be about 10% smaller than one side of the lower layer portion 33.

  The base coat layer 30 is provided below the first layer 31 a as the lowermost layer, and the overcoat layer 32 is provided on the sixth layer 31 f as the uppermost layer of the phosphorescent layer 31. These coat layers 30 and 32 are made of glass frit containing no phosphorescent pigment. The base coat layer 30 is useful for sharpening the corners as described later. On the other hand, since the phosphorescent pigment contained in the phosphorescent layer 31 has a large particle size, irregularities may be formed on the surface of the phosphorescent body 1 by the phosphorescent pigment. By providing the overcoat layer 32 that does not contain a phosphorescent pigment, the overcoat layer 32 is melted by firing the laminated body 3 to prevent unevenness on the surface and smooth the corners (edges) of the laminated body 3. Can be finished. In addition, by providing the coat layers 30 and 32 symmetrically in the vertical direction, the balance of the surface tension at the time of melting of the laminate 3 can be maintained, thereby preventing the occurrence of uneven surface tension and preventing variation in shape. Can do.

  Each layer constituting the phosphorescent layer 31 is thicker than the coating layers 30 and 32. By making the phosphorescent layer 31 thick, the content of the phosphorescent pigment per unit area can be increased efficiently. Further, since the coat layers 30 and 32 do not contain a phosphorescent pigment, the surface tension acts larger than that of the phosphorescent layer 31. As a result, the phosphorescent body to be molded can be finished smoothly, and the light emission performance can be improved efficiently.

  As the phosphorescent pigment, for example, a pigment obtained by adding and firing a rare earth element activator or a coactivator containing an alkaline earth metal aluminate compound as a main component is used. Examples of the alkaline earth metal include at least one metal element such as calcium, strontium, and barium, and alloys of these metal elements and magnesium. Examples of the rare earth element activator include europium and dysprosium. Examples of the co-activator include elements such as lanthanum, cerium, praseodymium, neodymium, samarium, cadmium, terbium, and dyspronium. In addition to the oxide phosphors described above, phosphorescent pigments include CaS: Bi (purple blue light emission), CaSrS: Bi (blue light emission), ZnS: Cu (green light emission), ZnCdS: Cu (yellow to orange light emission). It is also possible to use sulfide phosphors such as In addition, you may use the above-mentioned compound by mixing suitably, Furthermore, what has a luminous property in another inorganic fluorescent pigment or an organic fluorescent pigment can also be used.

  The material of the glass frit is, for example, at least one alkaline earth metal selected from the group consisting of silicon oxide, aluminum oxide, boron oxide and alkali oxide, and selected from the group consisting of calcium oxide, strontium oxide and magnesium oxide. Those containing oxides are used. The material of the glass frit is not limited to the above material, but a material that melts (liquefies) the above phosphorescent pigment at a temperature at which it can exist as a solid may be used. Further, it is desirable to use a glass frit material with high transparency after firing. The light emission of the phosphorescent pigment is not hindered and the light emission performance is prevented from being lowered.

  Here, the manufacturing process of the luminous body 1 according to the present embodiment will be described. This manufacturing process generally includes a mixture creating step for creating a paste-like mixture 2, a laminate forming step for forming the laminate 3 by laminating the created paste-like mixture 2 in a plurality of layers, and a laminate 3. And a firing step of forming into a desired shape by surface tension at the time of melting.

  In the mixture preparation step, each powder of phosphorescent pigment and glass frit and liquid medium are mixed to prepare a paste-like mixture 2. Here, it mix | blends so that a phosphorescent pigment may exist in the range of 1 to 40 weight% with respect to the total amount of a luminous pigment and glass frit. If it is in this numerical range, it can shape | mold to a desired shape with the surface tension at the time of the fusion | melting of the laminated body 3 in a baking process, without reducing the light emission performance by a luminous pigment. Then, an appropriate amount of liquid medium is mixed with the total amount of the prepared solid components (powdered phosphorescent pigment and glass frit) to prepare a paste-like mixture 2.

  In the present embodiment, for example, the phosphorescent pigment is blended so as to be 30% by weight with respect to the total amount of the phosphorescent pigment and the glass frit. And liquid medium is mixed with 40 weight% with respect to the total amount of the prepared solid component. That is, the mixture is prepared in the ratio of phosphorescent pigment: glass frit: medium = 3: 7: 4 to obtain a paste-like mixture 2.

  Here, as the medium 4, for example, one-component or two-component types such as acrylic, alkyd, epoxy, urethane, acrylic silicon, fluorine, and melamine can be used. The medium is not limited to the above materials as long as it forms a connection between the powdery phosphorescent pigment and the glass frit in order to form the granular phosphor 1. For example, squeegee oil or various binders can be used. In addition, at the time of preparation, additives such as a dye other than the phosphorescent pigment, glass frit, and medium may be added within a range that does not affect the light emission performance.

Next, a laminated body formation process is demonstrated.
In the present embodiment, the above-described mixture 2 is screen-printed on the transfer paper 20 as a support member by the printing machine 10 to form a plurality of the above-described laminates 3 at the same time. By applying screen printing, a large amount of the laminate 3 can be formed efficiently. Here, as shown in FIG. 3C, the transfer paper 20 is composed of a transfer layer 22 as a support layer made of a base paper 21 and a resin film, and a water-soluble adhesive layer 23 for bonding them. For example, what is generally used for painting a ceramic can be used. The transfer layer 22 may be any material that has adhesiveness to the laminate 3 and that burns away when the laminate 3 is fired. For the transfer layer 22, for example, an acrylic ester copolymer, a vinyl resin, a cellulose resin, and other resin materials such as hydrocarbons are used. The adhesive layer 23 is made of transfer paper paste such as starch, dextrin, polyvinyl alcohol, polyvinyl pyrrolidone, gum arabic, or water-soluble acrylic resin.

  First, as shown in FIG. 3A, the screen plate 12 ′ having the opening 13 is attached to the printing machine 10. The transfer paper 20 is placed on the table 11 and the transfer paper 20 is aligned with the screen plate 12 ′ attached. Here, the transfer paper 20 is fixed to the table 11 by a fixing member such as a tape so that positional displacement does not occur during screen printing. In the present embodiment, a 150-mesh screen is used for the screen plate 12 ′, and the base coat layer 30 is formed. If the base coat layer 30 that does not use a pigment is printed by the fine screen plate 12 ′, corner portions and the like can be formed sharply.

  Then, a paste-like glass material 2 ′ mixed with medium and glass frit is disposed on the screen plate 12 ′, and the squeegee is moved on the upper surface of the screen plate 12 ′. Thereby, the glass material 2 ′ is applied so as to be pushed out to the lower surface side through the opening 13, and is applied (printed) on the transfer layer 22 of the transfer paper 20, thereby forming the coat layer 30.

  Next, the screen plate 12 'is replaced with a screen plate 12 having a different mesh. Since the particles of the phosphorescent pigment are large, a screen plate 12 that allows the phosphorescent pigment contained in the mixture 2 to pass through the opening 13 is selected. Moreover, the luminous layer 31 can be made thick by using a screen plate having a larger opening than the above-described screen plate. Thereby, content of the phosphorescent pigment per unit area increases, and the luminous performance of the phosphor 1 can be improved. In this embodiment, the screen plate 12 is replaced with a 60 mesh screen plate 12.

  Then, as shown in FIG. 3B, the paste-like mixture 2 is arranged on the screen plate 12, and the squeegee 14 is moved on the upper surface of the screen plate 12. Thereby, the mixture 2 is applied (printed) through the opening 13, and the first layer 31 a of the phosphorescent layer 31 is formed on the upper surface of the base coat layer 30.

  By repeating this a plurality of times, as shown in FIG. 3C, the layers are stacked by the number of times of printing, and the stacked body 3 is sequentially stacked on the surface 22 a of the transfer layer 22. In the present embodiment, the phosphorescent layer 31 having a six-layer structure of the first layer 31a to the sixth layer 31f is formed by performing screen printing six times. Then, the screen plate 12 is replaced with a 150-mesh screen plate 12 ′ again, and the overcoat layer 32 is formed on the sixth layer 31 f of the phosphorescent layer 31.

  The shape of the opening 13 can be set as appropriate, such as a polygonal shape such as a triangle or a quadrangle, a circle, or an ellipse. Moreover, the opening 13 may be provided with a plurality of the same shape as in the present embodiment, or may be provided with a plurality of different shapes and sizes. In the present embodiment, the opening 13 has a substantially square shape, and a plurality of openings 13 are formed at appropriate intervals.

  By the way, the medium used for the mixture 2 and the glass material 2 ′ may contain an organic solvent containing carbon. In such a case, if the medium remains at the time of subsequent baking, the carbon of the organic solvent becomes soot and darkens, and the luminance of the phosphor 1 is lowered. Therefore, a drying process for drying the medium is provided every time one layer is formed. As a result, the organic solvent present in the layer is completely vaporized and eliminated, thereby preventing the luminance of the phosphor 1 from being lowered. In the present embodiment, each time the above-described screen printing is performed, the layer is dried to evaporate and evaporate the organic solvent. The drying step is performed, for example, by exposing to warm air for a predetermined time.

  After the laminate 3 is formed by screen printing a plurality of times, the transfer paper 20 is immersed in water as shown in FIG. Thereby, the water-soluble adhesive layer 23 is dissolved, and the transfer layer 22 is peeled off and separated from the mount 21 while the laminate 3 is held by the transfer layer 22.

Next, the firing process will be described.
In the present embodiment, as shown in FIG. 4, the plurality of laminates 3 are placed on the firing underlay 51 by the transfer layer 22 and moved to the furnace 50. By placing the laminate 3 on the underlay 51 in a position (orientation) on the transfer layer 22 and placing it in the furnace 50 and firing it at a predetermined temperature (for example, 800 ° C.), the surface tension of the laminate 3 is reduced. Mold by using. Further, the transfer layer 22 is burned away by firing. For example, an alumina sheet is used for the firing underlay 51, but there is no particular limitation as long as the laminate 3 is of a material or structure that does not sinter.

  Here, the surface tension is a tension acting along the surface so that the surface of the liquid contracts itself to have as small an area as possible. When the laminated body 3 is fired to melt, the glass frit contained in the laminated body 3 is melted to become a liquid glass component, and surface tension is generated in the laminated body 3. On the other hand, the luminous pigment has a higher melting point than the glass frit, and exists as a solid at the melting temperature of the glass frit. Therefore, the surface tension ST generated in the laminate 3 varies depending on the content (blending amount) of the phosphorescent pigment.

  In the present embodiment, the phosphorescent pigment is contained in an amount of 30% by weight based on the total amount of the prepared solid components (powdered phosphorescent pigment and glass frit). When the laminated body 3 is fired at a predetermined temperature (for example, 800 ° C.), as shown in FIG. 5, the substantially rectangular laminated body 3 is rounded at each side and corner due to the surface tension ST. With this surface tension ST, a substantially cubic shape phosphorescent body 1 is obtained.

Next, a second embodiment of the present invention will be described. In the following embodiments, the same members and the like as those in the above embodiments are denoted by the same reference numerals.
In said 1st embodiment, it mixed so that a phosphorescence pigment might be 30 weight% with respect to the total amount of a phosphorescence pigment and glass frit, the substantially square laminated body 3 was baked, and the phosphor 1 was obtained. However, in the second embodiment, the phosphorescent pigment is blended so as to be 5% by weight or more and 20% by weight or less based on the total amount of the phosphorescent pigment and the glass frit. If it is in this numerical range, compared with 1st embodiment, content of the luminous pigment of the laminated body 3 at the time of baking is small. Therefore, the surface tension ST generated during firing becomes large. Therefore, as shown in FIGS. 6A and 6D, it is possible to manufacture a spherical phosphor 1A. For example, it mix | blends so that a luminous pigment may be 10 weight% with respect to the total amount of a luminous pigment and glass frit.

  In such a case, the opening 13 of the screen plate 12 is preferably formed in a substantially circular shape in the laminate forming step. Moreover, in said 1st embodiment, the coating layers 30 and 32 which make a pair on the upper and lower sides of the luminous layer 31 of the laminated body 3 were provided. However, in the second embodiment, the coat layer 32 is not formed. The coat layer 30 may be provided as appropriate in accordance with the shape. The coat layers 30 and 32 can be provided only on one of the upper and lower layers.

Finally, the possibility of other embodiments is mentioned.
The shape of the phosphor 1 is not limited to the substantially cubic shape of the first embodiment or the spherical shape of the second embodiment. For example, it can be formed into a semispherical shape as shown in FIGS. 6B and 6E or a stepped substantially conical shape as shown in FIGS. In the first and second embodiments, as shown in FIGS. 2 and 7A, the phosphor layers 31 and 31 </ b> A of the laminates 3 and 3 </ b> A are formed by laminating the same mixture 2. However, the laminated body 3 can also be used in combination of a plurality of types of mixtures having different blending amounts of phosphorescent pigments.

  When forming into a hemispherical shape, for example, as shown in FIG. 7B, the laminated body 3B is formed in three steps having different areas of the lower layer portion 33B, the upper layer portion 34B, and the intermediate layer portion 35B in a step shape. Further, the upper layer portion 34B, the intermediate layer portion 35B, and the lower layer portion 33B are constituted by two kinds of mixtures having different contents of the phosphorescent material. In this example, for example, each layer of the upper layer portion 34B and the intermediate layer portion 35B is formed from a mixture having a phosphorescent pigment content of 10%, and each layer of the lower layer portion 33B is formed from a mixture having a phosphorescent pigment content of 30%. The smaller the phosphorescent pigment content, the smaller the amount of phosphorescent pigment present as a solid component in the molten state of the laminate. Accordingly, the smaller the phosphorescent pigment content (the smaller the blending amount), the greater the surface tension in the molten state. Accordingly, in this example, the upper layer portion 34B and the intermediate layer portion 35B have a large surface tension and become spherical. As a result, it is formed as a hemispherical phosphor 1B.

  Further, when forming into a stepped substantially conical shape, for example, as shown in FIG. 3C, the laminated body 3C is made of 3 layers having different areas of the lower layer portion 33C, the upper layer portion 34C, and the intermediate layer portion 35C as described above. A seed layer is formed in a staircase pattern. And each part 33C-35C is formed with 3 types of mixtures from which the content rate of a luminous pigment differs. In this example, for example, the lower layer portion 33C is a mixture having a phosphorescent pigment content of 30%, the intermediate layer portion 35C is a mixture having a phosphorescent pigment content of 20%, and the upper layer portion 34C is a laminate having a phosphorescent pigment content of 10%. 3C is generated. In this example, the surface tension acts more toward the upper layer portion 34B. As a result, it is formed as a substantially conical phosphorescent body 1C.

  In each of the above embodiments, the layers of the stacked body 3 are formed in a stepped shape with different areas. However, it is not limited to the step shape, and the arrangement of a plurality of types of layers having different layer areas can be set as appropriate. Furthermore, in each said embodiment, the thickness of the several layer of the laminated body 3 was made the same. However, the laminate 3 can also be composed of a plurality of types of layers having different layer thicknesses.

  Thus, the phosphorescent body 1 having a desired shape can be manufactured by appropriately selecting and combining the blending amount of the phosphorescent pigment and the shape of the laminate 3 to adjust the surface tension in the molten state of the laminate 3. it can.

  In the laminated body formation process in the first embodiment, the 60-mesh screen plate 12 is used for screen printing six times to form the phosphorescent layer 31 having a six-layer structure, and the 150-mesh screen plate 12 ′ is used. The cover coat layer 32 was formed. However, the mesh of the screen plate and the number of times of printing are not limited to these, and can be appropriately selected.

  Moreover, in said 1st, 2nd embodiment, each layer of the luminous layer 31 of the laminated body 3 was formed using the screen plate 12 of the same mesh. However, the layer can also be formed by combining a plurality of screen printings using different mesh screen plates.

  In the second embodiment, screen printing was repeated a plurality of times to produce a spherical phosphorescent body 1A. However, the production of the spherical phosphor 1 </ b> A is not limited to screen printing. For example, the spherical phosphor 1 </ b> A is manufactured by dropping a droplet of the mixture 2 onto the transfer paper 20 and forming the drop on the baking underlay 51 and baking it. It doesn't matter. In each of the above embodiments, brush coating or spraying can be applied in addition to screen printing.

  In the first embodiment, instead of using the transfer paper 20 having the transfer layer 22, the support layer 40 may be formed from above after printing the laminate 3 as shown in FIG. 8, for example. The support layer 40 is made of a material such as the adhesive layer 23 in addition to a resin material such as an acrylate copolymer, a vinyl resin, a cellulose resin, and other hydrocarbons. The support layer 40 is not particularly limited as long as the support layer 40 is a material that has adhesiveness to the laminate 3 and is burned off when the laminate 3 is fired. Then, the plurality of laminates 3 together with the support layer 40 may be moved and placed on the underlay 51 and fired. Thereby, the support layer 40 is burned out and the phosphor 1 is generated.

In particular, the phosphor stored in the manufacturing method according to the present invention can be used as, for example, a nail stone, and can also be used as an accessory such as an artificial jewel.
